Hi all,

I have been struggling to create the geometry but at the final stage which is "Form Union", I am getting this error: "Geometry error (fin): Internal error in geometry decomposition."

Attached my model.
Could you kindly tell me how is it possible to solve this problem?

Thanks
Sepideh

Without looking at your file, I find that a good way around this error you are getting is to go back to your geometry and disable all geometry creation elements. Then start enabling them one at a time. Now mesh each individual step and activate more nodes as you go further along in your geometry. It is possible that one step in your geometry tree is causing problems. You can then isolate the problem and then try to figure out a work around.

I have had the same problem several times.
If you go to the "Form Union " and change the " Relative repair tolerance " by one or two orders of magnitude, it might solve your problem.
